3426430 - Compound key column(s) must be defined either in Dimensions or in Filter in order to make a consistent

All compounding parents need to be added to the rows or filtered on a constant value during the Analytic Model preview.

The functionality is not supported. Therefore, a remodeling approach is recommended. 
If the functionality of being able to see the information without all the keys being specific to the dimension is required, add a new attribute (which is not key) that duplicates the information.
